Pebeo Drawing Gum

Pébéo Drawing Gum is ideal for preserving white areas on your paper for watercolour and airbrush. It is a removable grey liquid frisket that is water soluble when wet, but dries waterproof. Excellent for fine detail work.

Apply with a brush (not your best one), a Color Shaper, Incredible Nib, or cotton bud. Removes easily from most papers with a finger, rubber cement pick-up, or soft eraser. As with all liquid masks, be sure not to leave on your painting too long, and be sure to do a test on any surface that you haven’t used it on previously.

Winsor & Newton Aquapasto Medium

Add some extra gloss and texture to your watercolour and gouache paintings.

This translucent gel medium reduces flow, and thickens watercolours and gouache to give them a pleasing textural impasto effect and extra gloss. Mix it with the paint, or use it pure by layering on the surface of the paper prior to painting.

Winsor & Newton Iridescent Medium

This specialty medium adds a pearlescent or glitter effect to watercolours, and can be mixed directly with watercolours, or applied over a dried wash. The iridescent effect works well when applied over darker colours or on darker paper. Try experimenting with different shades of paper for your own unique techniques and effects.

Da Vinci Gum Arabic

Use the Da Vinci Gum Arabic to gain more control over the flow of your watercolour paint when working wet-on-wet. It will also increase transparency and gloss. 59 ml.

Da Vinci Masking Fluid

• Shipping charges may apply.

Let your exquisite watercolour paper shine through with an easy to remove masking fluid.

Da Vinci Masking Fluid is excellent for reserving the original colour of your painting surface, whether it is watercolour paper or board. This product is easy to apply using a brush, and is quick drying and non-staining.

The masking fluid can be easily removed by means of rubbing with an eraser or rubber cement pick-up. It should only be applied to dry surfaces. Before removing, make sure your artwork is completely dry. Avoid leaving it on too long before removal; due to its tacky consistency it can be harder to remove, as well as stain.
